摘要
摄像机标定是立体视觉三维重构的基础,标定的精度、稳定性和效率决定着整个双目立体视觉系统的性能。通过改变标定板图像数目开展标定实验,分别获得了摄像机内参和外参、标定所需时间,分析了标定板图像数目与标定精度和标定效率之间的关系。实验结果表明,对双目立体视觉而言,标定板图像数目为10幅为宜。
Camera calibration is the foundation of stereo vision and 3D reconstruction. The performance of the stereo vision system depends on the accuracy,stability and efficiency of calibration. In this paper,calibration experiments were carried out through changing the number of target image,the inner and exterior parameters,and consuming time were obtained. The relationship between the number of target images and calibration accuracy and efficiency. Experimental results show that ten target images will be proper in for stereo vision system.
